What will be the sign of the result of the exercise?
We will only look at whether the number is negative or positive.
In other words, the division exercise looks like this:
If we solve the exercise from left to right, we will first divide plus by minus:
Now the remaining exercise is:
Therefore, the sign of the exercise result will be negative.

Solve the following exercise:
\( (+6)\cdot(+9)= \)
When determining just the sign of a result, you can ignore the actual values! The sign rules for division work the same whether you're dividing 24 by 8 or 2400 by 0.8 - positive divided by negative always gives negative.
Same signs = positive, different signs = negative. Think of it like this:
Work left to right step by step! For , first solve , then . Each division creates a new sign to use in the next step.
Not at all! Decimals follow the same sign rules as whole numbers. Since 12.4 is positive, dividing by it follows the normal positive division rules. The decimal point doesn't change whether a number is positive or negative.
Count the negative numbers in your division chain. If you have an odd number of negatives, your result is negative. If you have an even number of negatives, your result is positive. Here: only -8 is negative (1 = odd), so result is negative!
